A lot of great suggestions above. Personally I think speaker synergy is very important. My 10 watt Dennis Had Inspire SEP drives my 99 dB Klipsch beautifully, superb holographic sound stage. Everything sounds like being there! It takes my beefy 23 watt 300b/845 SET to drive my Focal Aria @92 dB. And BION, a cheap Olchen EL34 that really only puts out about 5 watts before distorting above 3-5% sounds great paired with Vienna Acoustics @92 dB. I swapped out the stock Psvane tubes for NOS Svetlana and Tesla EL34s with Tung Sol and Sylvania FAA 6SN7s. It’s my master bedroom rig playing early morning and late night low volume jazz, folk, etc. sound very clean, detailed and warm.
So, for SS, and I’ll probably get a lot of haters here, but I also have a vintage Crown DC 300A and IC150 preamp that sounds amazing driving a pair of vintage Infinity 4 way towers. Different sound than tubes, but great imaging, tight punchy bass, warm, yes warm mids, and sparkling highs. And it can play loud, loud! Rock, country, let’s get the party started!
You’ll have no problem driving 96 dB studio monitor speakers with 25-50 SS watts. Never heard a Pass Labs, but everyone loves them…however $$$$! The Kinky reviews are good and only $3500 ish. If this is a temporary solution, I’d pickup an integrated SS reliable brand like Cambridge Audio or Luxman off ebay or audio mart. If you’re budget bigger, there’s always a used McIntosh! Only brand that holds its value like a used Ferrari.
